经常有客户在购买橡胶软接头过程中提到，之前所用的橡胶软接头质量太差，橡胶太软，会被水泵吸扁，想采购一些质量好的、硬一点的橡胶软接头。 Guide: Many customers mentioned in the process of purchasing soft rubber joints that the rubber soft joints used before were of poor quality and the rubber was too soft, which would be sucked by the pump.
Customers often mentioned in the process of purchasing soft rubber joints
that the rubber soft joints used before were of poor quality and the rubber was too soft and would be sucked by the water pump. Later, after careful communication with the customer, the soft rubber joint was flattened mainly because the interior of the pipeline was in a vacuum state, which is what we call the pipeline with negative pressure. According to this situation, the technicians of Shanghai Luoying Pipeline Equipment Co., Ltd. have developed a new type of soft rubber joint that can withstand negative pressure, which mainly solves the problem of negative pressure in the pipeline.
The soft rubber joint mainly bears the internal pressure of the pipeline. It can bear a little negative pressure itself, but the negative pressure it bears is very small. For example, the rubber soft joint of DN300mm, in the 1.6Mpa pressure level, it can only withstand the vacuum. 86kpa, but in the actual working environment, the negative pressure of the soft rubber joint is far greater than this value, which causes the phenomenon of the rubber soft joint being flattened. Generally, the rubber soft joint that is flattened mostly occurs in the pump. Water side. The negative pressure-resistant rubber soft joints produced by Shanghai Luoying Pipeline Equipment Factory are equipped with a negative pressure-resistant device internally. The negative pressure-resistant device can ensure that the soft rubber joints are not flattened, so that the original soft rubber joints are not affected. It is an ideal soft rubber joint that can withstand negative pressure.
Negative pressure resistant soft rubber joints are new products independently developed by our company. They are mainly used in pump inlets and outlets, vacuum pipelines and tailings pipelines. Negative pressure resistant soft rubber joints are structurally the same as normal positive pressure rubber soft joint products. There is a big difference. Compared with general rubber joint
products that bear positive pressure, there are more negative pressure resistant devices to ensure that the soft rubber joints with negative pressure resistance will not flatten when subjected to negative pressure.
Therefore, when choosing soft rubber joints, we must implement whether there is negative pressure (ie, vacuum) in the pipeline. If negative pressure (ie, vacuum) occurs, we must choose negative pressure resistant rubber soft joints to avoid soft rubber joints. The connector is flattened and leaks occur.
